I'm wondering if there are performance issues with WD- Black hard drives.
On one of my Wife's Win10 machine, there was constant disk activity that
I could not trace down...all seemed normal.
I decided to clone the drive to a SSD and found a nice improvement that
I thought was simply a function of the SSD.
Then realized that on my main machine running Ubuntu 20.04 that also had
a WD-Black drive, there also seemed to be excess drive activity. Since I
have not done a disk clone backup in years, I cloned the drive to a
Seagate SATA and found the excess drive activity had been cured.
At the time I purchased the WD-Black, I thought I was getting a top of
the line drive.

If it's a recent drive, it may be using the inferior Shingled Magnetic Recording
(SMR) technology. See
https://www.extremetech.com/computin...drives-use-smr
for a list of which drives use the lower performance recording method.
